Get only one page after search spidering

I get only one page in the search spidering. Iā€™m trying to crawl the site to search robots, but I get only one result (index.html). It seems that the spider does not crawl the site folders and does not see sitemap.xml . Please give advice

Hello @ggavrilov can you send us the URL of your project, and the URL of the website you are trying to crawl at support@datocms.com so we can check what could be happening?

Thank you!
